The adjusted stats are simply the stats for each team adjusted for their competition. Per game stats are adjusted giving equal weight to each opponent, however the per play stat adjustments are a little different. As an example, Team A plays Army and Oklahoma. If Army has a passing efficiency of 100 and Oklahoma has a passing efficiency of 200, simply averaging Team A's opponents' ratings will put their expected defensive passing efficiency allowed at 150. However, if Army attempts only 5 passes against Team A while Oklahoma attempts 45, this is clearly incorrect. The true expected defensive passing efficiency should instead be 190, weighted for the number of pass attempts faced against each opponent. This is how the adjusted per play stats are calculated. A more detailed explanation of the theory and calculations is available in the 2009 Year in Review document available within the data menu above.

Available seasons' game reports and extremes tables can be accessed via the DATA menu above. All stats are available for seasons beginning in 2008, the 2000-2007 use estimated net punting numbers and do not have kickoff, time of possession, sacks, or conversion statistics. Many thanks, in fact an indescribable amount of gratitude, to Ed at The National Championship Issue for the pre-2008 data that he made available.

Within the adjusted stats pages, total passing and total rushing refers to moving sacks and sack yardage from the rushing figures - where the NCAA includes sack results - to the passing figures. This allows us to better understand a team's pass offense/defense compared to their run offense/defense. As noted above, however, sack information is unavailable for seasons prior to 2008 so the total passing and total rushing figures will be identical to the regular passing and rushing stats. Also prior to 2008 overtime information is limited to whether or not there was at least one overtime in the game, so all overtime games from that period will state "1OT" on the team schedules.
